Intshayelelo:
I-roller coating iye yaba yindlela ekhethwayo yokufaka ii-coating kwi-aluminium coils ngenxa yokusebenza kwayo kakuhle nokusebenza kwayo. Ngenxa yokwanda kwemfuno yeemveliso ze-aluminium ezifakwe i-coating ezisemgangathweni ophezulu nezihlala ixesha elide, i-roller coating iye yaba yinkqubo ebalulekileyo kwishishini le-aluminium. Nangona kunjalo, ukuze kufezekiswe iziphumo ezinqwenelekayo, kubalulekile ukuqonda iimfuno ezithile zokusebenza kwe-roller coating. Kule blog, siza kujonga kwiimfuno eziphambili zokusebenza ekufuneka ii-roller coating coating coating coating zifezekise, sigxile kwi-viscosity kunye ne-leveling properties, ukuphiliswa ngokukhawuleza, iimpawu zokuhombisa, kunye nokumelana nemozulu.
1. I-viscosity efanelekileyo kunye neempawu ezilungileyo zokulinganisa:
Inkqubo yokugquma i-roller ibandakanya ukondla ngebhanti ngokukhawuleza, ukugquma i-roller, ukubhaka kubushushu obuphezulu, kunye nokupholisa ngokukhawuleza. Ukuqinisekisa iipropati ezifanelekileyo zokulinganisa, kubalulekile ukuba i-roller yokugquma ifake inani elaneleyo lepeyinti kwizinto ze-aluminiyam. Ke ngoko, ii-roller coating coating coating kufuneka zibe ne-viscosity efanelekileyo kunye neempawu ezilungileyo zokulinganisa. I-viscosity ye-coating kufuneka yenziwe ngononophelo ukuvumela ukusetyenziswa okulula ngelixa igcina amandla ayo okulinganisa ngokulinganayo kumphezulu we-aluminiyam. Ukufikelela kwi-viscosity balance efanelekileyo kubalulekile ekuthinteleni imiba efana nobukhulu be-coating obungalinganiyo, imicu, kunye nemiphumo ye-orenji peel.
2. Ukulungiswa ngokukhawuleza:
Ngenxa yendlela esebenza ngokukhawuleza ngayo imigca yokuvelisa i-roller coating, ukucocwa ngokukhawuleza kuyimfuneko ebalulekileyo kwiingubo ze-roller coating. Ngaphandle kwenkxaso kunye nobude obuncinci be-oven yokubhaka, ixesha elikhoyo lokupholisa ipeyinti liyancipha kakhulu. Iipeyinti ezisetyenziswa kwi-roller coating kufuneka zenziwe ukuze zicocwe ngaphakathi kwexesha elifutshane, kungcono ukuba zingaphantsi kwemizuzwana engama-60. Ukongeza, inkqubo yokucocwa kufuneka igcine ipeyinti ingaphantsi kobushushu be-coil obuyi-260.°C ukuthintela ukuba izinto zingaguquguquki okanye ezinye iziphumo ezingathandekiyo. Ukukhetha isinyibilikisi ngokufanelekileyo kuyimfuneko ukuze kufezekiswe ukuchacha ngokukhawuleza ngaphandle kokubeka esichengeni ukuthembeka kwengubo, kuthintelwe iingxaki eziqhelekileyo ezifana nokubhoboza, imingxunya yemingxuma, kunye nokungalingani kakuhle.
3. Iimpawu zokuhombisa:
Ngaphandle kweempawu ezisebenzayo, iingubo zokugquma ezijikelezayo kufuneka zihlangabezane neemfuno zokuhombisa. Ipeyinti yepolyester idla ngokwanela ukufezekisa inkangeleko enqwenelekayo ngokusetyenziswa kanye. Nangona kunjalo, xa usebenzisa i-fluorocarbon coating, i-primer kunye ne-topcoat ziyafuneka ukuze ufumane iziphumo zokuhombisa ezifanelekileyo. I-primer kufuneka ibe nokumelana okuhle kokugqwala kunye nokunamathela kwi-substrate kunye ne-topcoat, ngelixa i-topcoat kufuneka ibonise amandla amahle okufihla kunye neempawu zokuhombisa. I-primer enye elandelwa yi-topcoat enye inokubangela inkangeleko entle ehlangabezana neemfuno zobuhle kunye nokusebenza.
4. Ukumelana nemozulu:
Iingubo zokugquma ezijijekayo kufuneka zibonakalise ukumelana nemozulu okungaqhelekanga, ngakumbi xa zisetyenziswa kwiimveliso ze-aluminium zangaphandle. Iingubo ze-PVDF fluorocarbon zihlala zisetyenziselwa ukubonelela ngokusebenza okubanzi ngokuchasene nezinto ezinje ngokuqina, imvula ene-asidi, ungcoliseko lomoya, ukugqwala, amabala amileyo, kunye nomngundo. Ngokuxhomekeke kwiimfuno ezithile zendawo, iingubo ezimbini, ezintathu, okanye ezine zengubo ye-PVDF zingasetyenziswa. Oku kuqinisekisa ukhuseleko oluhlala ixesha elide kunye nokuqina okuphezulu, okuvumela i-coil ye-aluminium ejijekileyo ukuba imelane neemeko ezinzima zokusingqongileyo.
Isiphelo:
Ukuqukumbela, ukufikelela ekusebenzeni kakuhle kwe-roller coating kwiikhoyili ze-aluminiyam kufuna ukuqwalaselwa ngononophelo kwe-viscosity kunye neempawu zokulinganisa i-coating, amandla okunyanga ngokukhawuleza, iimpawu zokuhombisa, kunye nokumelana nemozulu. Ngokuqonda nokunamathela kwezi mfuno zokusebenza, abavelisi banokuvelisa iimveliso ze-aluminiyam ezigqunywe ngomgangatho ophezulu ezihlangabezana nemigangatho efunekayo yemizi-mveliso eyahlukeneyo. Njengoko imfuno yeekhoyili ze-aluminiyam ezinokuthenjwa nezibukekayo iqhubeka ikhula, kubalulekile ukubeka phambili ukukhethwa kunye nokusetyenziswa kweekhoyili ze-roller coating ezinokuhlangabezana nezi mfuno zibalulekileyo zokusebenza.
